I'm using the wikibase.cloud beta. Quickstatements works with my subdomain instance https://prosop.wikibase.cloud/tools/quickstatements/#/ but my custom url instance https://ottgaz.org/tools/quickstatements/#/ hangs on loading.

Cradle also hangs in the custom domain but not in the subdomain. Query works in the custom domain.

Any suggestions?

I've also filed this as an issue: https://github.com/wbstack/quickstatements/issues/101
